https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D272286 --- Comment #2 from Jonas Lopes <jonasbsd@gmail.com> --- (In reply to Mina Gali=C4=87 from comment #1) Hi Mina, On the nose! It was SNDIO arresting the process. After I stopped the service: # usbconfig list ugen0.1: <Intel XHCI root HUB> at usbus0, cfg=3D0 md=3DHOST spd=3DSUPER (5.= 0Gbps) pwr=3DSAVE (0mA) ugen0.3: <Dell Computer Corp Dell Universal Receiver> at usbus0, cfg=3D0 md= =3DHOST spd=3DFULL (12Mbps) pwr=3DON (100mA) ugen0.4: <Chicony Electronics Co.,Ltd. Integrated Camera> at usbus0, cfg=3D0 md=3DHOST spd=3DHIGH (480Mbps) pwr=3DON (500mA) ugen0.5: <vendor 0x8087 product 0x0a2a> at usbus0, cfg=3D0 md=3DHOST spd=3D= FULL (12Mbps) pwr=3DON (100mA) After I plugged the sound card back in: # usbconfig list ugen0.1: <Intel XHCI root HUB> at usbus0, cfg=3D0 md=3DHOST spd=3DSUPER (5.= 0Gbps) pwr=3DSAVE (0mA) ugen0.3: <Dell Computer Corp Dell Universal Receiver> at usbus0, cfg=3D0 md= =3DHOST spd=3DFULL (12Mbps) pwr=3DON (100mA) ugen0.4: <Chicony Electronics Co.,Ltd. Integrated Camera> at usbus0, cfg=3D0 md=3DHOST spd=3DHIGH (480Mbps) pwr=3DON (500mA) ugen0.5: <vendor 0x8087 product 0x0a2a> at usbus0, cfg=3D0 md=3DHOST spd=3D= FULL (12Mbps) pwr=3DON (100mA) *ugen0.2: <Kingston HyperX Amp> at usbus0, cfg=3D0 md=3DHOST spd=3DFULL (12= Mbps) pwr=3DON (100mA)* The `procstat -a -k` command ran to completion without any problems. It did= not show any hanging. I think it's interesting to have a callback in the USB processes to signal = when something has been unplugged and to detach the reference. Such as, "hey snd= io, virtual_oss, pulse, etc, that sound card was unplugged. Take it off your li= st". Mina, thank you very much!!!
